How Bit Image Graphics Are Produced

The binary data byte bit pattern for the ASCII character “A” (hex 41, decimal 65) is pictured in Figure 4–2.

•If this data byte is rotated clockwise, the result is a vertical data byte pattern with the MSB at the top.

•If each “1” or true bit is plotted, the result is a Bit Image plot of the ASCII character “A.”
